Abstract

Eine Vordrossel sowie Meßdüsen sind in Reihe hintereinander angeordnet, und zwar derart, daß sich der Drosselwiderstand der Meßdüse mit Abmessungen eines Werkstückes ändert. Vor und hinter der Vordrossel sind Drucksensoren angeschlossen, so daß einerseits der pneumatische Überdruck gegenüber der Atmosphäre vor der Vordrossel sowie andererseits der Druckabfall an der Vordrossel ermittelbar sind. Damit kann unmittelbar ein die Abmessungen des Werkstückes wiedergebendes Signal ermittelt werden.A pre-throttle and measuring nozzles are in a row arranged, in such a way that the Throttle resistance of the measuring nozzle with dimensions of a Workpiece changes. In front and behind the choke are Pressure sensors connected so that the one hand pneumatic overpressure against the atmosphere the pre-throttle and on the other hand the pressure drop can be determined on the pre-throttle. This can be done immediately a representing the dimensions of the workpiece Signal can be determined.
